In the environment, algae are exposed to several stressors such as limitation of essential nutrients and excess of toxic substances. It is well known the importance of phosphorus (P) supply for healthy metabolism of algae and impacts at this level can affect the whole aquatic trophic chain. Aluminum (Al) is the most abundant metal on Earth and it i...

Anaerobic digestion piggery effluent (ADPE) shows high chromaticity and ammonium levels, severely inhibiting algal growth. Fungal pretreatment has great potential for decolorization and nutrient removal from wastewater, which coupled with microalgal cultivation may be a reliable strategy for sustainable ADPE resource utilization. In this study, we ...

Floating Treatment Wetlands (FTW) are a promising solution for improving the quality of wastewater discharges, yet they exhibit a wide range of Total Phosphorous (TP) removal performances, raising uncertainty about their reliability. This study investigates the potential of enhanced FTW equipped with recycled cellular concrete (CC) to improve the p...

Wastewater management (WWM) is an issue in low and middle-income countries' rural areas; the lack of technology and funding have been identified as the most critical. Marcelino Maridueña (MM) is a rural village in Ecuador that uses an oxidation pond to treat its household wastewater. As a result, the organic load in the effluent varies depending on...

Fifteen microcosms were installed in the Åkerberg pit lake for 15 days in the summer season (July) 2021. To stimulate algal growth, the microcosms were fertilized with two P-rich wood ashes, and KNO3. Chlorophyll-a was used as an indicator of algal growth while filtered (0.2 μm) were used to estimate algal metal uptake. Water quality measurements a...

Conventional methods for recovering heavy metals from industrial waste stream often involve significant energy consumption and chemical use. Hence, using microalga as a biosorbent material can be a low-cost and eco-friendly solution. Galdieria sulphuraria is a red microalga which is known to be capable of recovering heavy metals. This algal species...

Climate change and increasing world population call for careful utilization of water and energy sources. Microalgae to treat wastewater in a coupled process to produce biofuels and other value-added products for human consumption are promising solutions. An analysis of culture parameters and cultivation processes is presented as essential to achiev...

Oxytetracycline (OTC) and enrofloxacin (EFX) pollution in surface water are very common. Using the algal-bacterial consortia system to remove antibiotics remains to be further studied. In this study, the algal growth and sewage purification performance were studied in an algal-bacterial consortia system with different concentrations of antibiotics....

Algae is an appropriate natural resource to augment the optimal use of undesired ions in water and wastewater. Increasing algal cells, the consumption of particular ions, including chloride, nitrate, phosphate, and ammonium, provides a suitable way to optimize water treatment processes. Different algal species have the capability to survive in extr...

The potential of Scenedesmus dimorphus microalgae for CO2 biofixation and lipid biosynthesis for bioenergy applications was evaluated in this study. Batch experiments were conducted using synthetic tertiary municipal wastewater samples at several nitrogen to phosphorus (NP) ratios (1 : 1 to 8 : 1) and CO2 concentrations (∼0%, 2%, 4%, and 6% CO2 in ...
